• Spoke at GR8Conf about microservice test automation.
• Talk synopsis:
• "This presentation will focus on simple techniques and patterns you can use for microservice test automation, specifically when testing services built with Gradle. The focus is not on end-to-end tests, but on functional, smoke, and load tests that reliably and quickly test services. Technologies covered include Gradle, Spock, Gatling, continuous integration/deployment/testing, Zipkin, and code generation.”
